This invention relates to washing machines, and more particularly towashin machines of the upright oscillator type, w erein the tub memberis fashioned with a plu- 5 rality of blade or bafiie members upon thebottom thereof, the same being adapted to create a violent water action.

One of the objects of the invention is in the provision'of a washingmachine of the upright oscillator type, the reciprocated tub member beinfashioned with a plurality of blade or ba e members upon the bottomthereof, the same being fashioned in a mannor to create a turbulentwater action and therefore to cleanse the clothes content in aremarkably short time.

Another object is in the provision of a washing machine of the typewherein a tub member is reciprocated by power mechanism, said tub memberbeing fashioned with wateraglitating means upon the bottom thereof, w

ereby the reciprocation of the tub and the action of the bladesco-operate to cleanse the clothes in a very short t1me.

Still another object is in the provision of an upright tub member, powermeans for reciprocating same and blades disposed in the bottom of thetub, the side walls of the tub being free from obstruction, and a bafiledisposed intermediate of the tub and projecting upwardly from the bottomthereof, providing not only a drain mechanism for the tub, but alsomeans for preventing entangling of the clothes during the washingoperation.

A further object is in the provision of an upright tub member, powermeans for reciprocating same, said tub member being provided with aplurality of spaced blade members upon the bottom thereof, said bladesbeing raised a suflicient distance from the bottom to create a violentwater action and being fashioned in a-manner to prevent excess wear uponthe clothes during their violent reciprocation.

A still further object lies in the provision of an upright tub member,power means for reciprocating same, said tub member having bottomportion thereof said water-agitating water-agitating means,

.means being raised sufiiciently from the bottom thereof to create aviolent water action,

and thereby cleanse the clothes content in a remarkably short time.

Referring to the drawings, in Fig. 1 there is shown in detail my uprightoscillator type of washing machine, wherein a frame portion is shown at10, securely attached, as at 11, to a supporting and housing portion 12,the same surrounding the tub and power means for the washer. Fixedly'attached to the lower endof the housing 12, as at13, are the plural legportions 14, there being provided conventional connecting means 15between same. A rim for the top of the housing 12 is shown at 16, thesame being adapted to enclose a substantial part, of the upper end ofthe washing machine, or rather, the tub member thereof. Secured, as at17, to the support or framing structure 10," is a bearing portion 18, ofsubstantial length and disposed vertically, as may be clearly seen inFig. 1. This elongated bearing portion 18 provides a.bearing surfaceboth upon the inner and outer part of its up er surface.

secured in any suita therefor,

late 23 and the reach members lies in the efore mentioned frictionelements 21. This frictional driving means provldes not onl 5 thedriving connection between thetub and power means, but also a means forpreventmg vibration during such reciprocation.

The tub is preferably constructed with the side wall curved inwardly asindicated at 32. Means for reciprocating the reach members 19 isprovided in the pltman 26 the same being connected to the reach membersat one end and having the pivotal connection 27 at its other end with acrank 28. Means for rotatin the crank 28 is rovided in a vert1- cal stufixedly attached, as at 30, at its upper end. The vertical stub shaft issuitably supported in the supporting frame 10 at a point ad acent itsupper end, and at ts bottom in a bearing 31 formed in a suitably arraned gearin housing also attached to the housing 12 an sup ort 10. Meansfor rotating the vertical stu shaft is provided in the worm gear 33 andan adjacent worm 34. A conventional pulley 35 isattached to the dIlV-ing end of the worm and said pulley depends for its rotation upon a belt35", the same emg driven by the conventional electric motor 36. Thebefore mentioned downwardly pro ecting stem 25, which centers the tub24, has an opening through its center portlon, as shown at 37, saidportion openlng into a drain mechanism 38 adapted to carry off the waterthrough the tub through the tube or outlet 39 to any point desired.

With respect to the tub 24, a plurality;J blades or bafiie's 40 aredisposed upon he ottom of the tub, said blades being raised asubstantial distance from the bottom thereof and adapted to create aviolent disturbance of the water contents during reciprocation of thetub. These blades or bafiles operate in substantially the same manner asthe blades upon a reci rocating disk in the well known t pe of was er,wherein the dolly ortion is disposed upon the bottom and the b desproect upwardly therefrom and are reciprocated in a manner to create aviolent water action.

In the resent instance violent water action is not or y created by-theaction of the u wardly' projectin b ades, but also by t e reciprocationof t e tub and it is apparent that the clothes content is continuouslymoved by the water action in a manner to yen shaft 29, to w ich saidcrank is cleanse same as well as to be agitated by the blades recirocating with the tu The blad ends, as'shown at 41, to prevent excesslvcwear upon the clothes content during recip roc'ation. In Figs. 1 and 2the blades are shown merging with the wall of the tub at positionsapproximately corres onding with the curved ortion 32, while t e innerends are rounde and pro ect merely to a point adjacent the centralportion of the tub. In other words, the outer extremities of the top edes of said blades are curved upwardly the contiguous ortions of the side0 the tub at positions he ow the lane of the upper end of said bafliemem r. The inner extremities of the top edges of the blades are extendeddownwardly to the bottom of the tub at positions spaced radially fromsaid baiiie member. In these figures, a vertically disposed baflie orsleeve 42 either forms a part of, or is attached to, the bottom of thetub, the same operating to supportthe drain mechanism WhlCh comprises adrain plug or valve 43' adapted to seat in=a draina e aperture in thebottom of the tub, a vertical y disposed manually operated screw or lugmember 45 attached to the upper end of member 44 and adapted, by manualmovement to raise the dram plug from its seat and therefore permit thedraining of the tub. Apertures 46 permit entrance of the water contentin the tub to a 43". as. c

It might be said at this point that the baflie or sleeve 42 not onlyacts as a means for supporting the tub drain mechanism, but also as acentrally disposed member of relatively small diameter for preventingentangling of the clothes content during reciprocation of the tub, orrather during washing 0 oration.

In the remaining figures of the d r awin'gs, the washing machinestructure and means for reciprocating the tub has not been changed, butmerely the manner of battling the tub has been disclosed in variousmanners. For instance, in Figs. 3 and 4, the blades 40 do not merge withthe side walls of the tub, but merely lie adjacent the bottom and mergewith the stem 42.

In Figs. 5 and 6, the blades are exactly the same shape as those shownin Figs. 1 and 2 of the drawings, but the central stem has been removedand the drain opening has merely a threaded plug or valve 47 insertedtherein. In this instance the draining of the tub is accomplished byremoving the plug or valve 47.

In Figs. 7 and 8, the drain mechanism is pfovided in a conventionaldrain opening 48 and valve 49, said drain mechanism being disposedexteriorly of the tub and at such a point that the entire water contentof the es 40 are rounded at their upper plug controlling member 44, anda I point about the drain plug or valve inwardly and gradually mer edinto r tub is adapted to be drained therefrom by merged at anintermediate point 50, as

shown in Fig. 8. In this instance, also, there is no centrally disposed,upwardly projecting bafile to prevent entangling of the clothes or tosupport a drain mechanism.

Having described in detail the washing machine, and particularly thebladed tub portion, it might be said that the reach members 19 arereciprocated in the manner described herein, the same being of wellknown construction and devised, in the first instance, by the presentapplicant.

Although the present tub is disclosed as being round, nevertheless itisobvious that a tub fashioned either substantially rectangular in shapeor with plural side portions,

might similarly have disposed upon its bottom upwardly projecting blademembers adapted to create a violent water action during reciprocation ofthe tub.

A removable cover is adapted to be placed upon the inwardly projectingends 51 of the tub and it is apparent that the 'rim 16 may be removedand the tub portion manually removed by simple vertical lift. The sideportions of the tub are flared slightly, as shown clearly at 52, andalso the connection between the side portions and the bottom of the tubis an unobstructed curved portion 53. It is thought from the above thatthe operation of themachine will be clear, and that the reciprocation ofthe tub will also cause reciprocation of the blade portions to create aviolent water action and therefore a quick cleansing of the clothescontent. The clothes are adapted to move in the path of the waterdisturbed by the upwardly projecting blade portions, and by thereciprocation of the tub itself, such movement being aided to someextent by the curvature of the tub wall near the bottom thereof. Saidcurvature also aids in directing flow of waterto the drainage aperturein the bottom of the tub, so as to facilitate emptying of said tub.

What I claim is:

1; In a washin machine, a tub, a centrally located b e member ofrelatively small diameter extending upwardly from the bottom of the tub,and a plurahty of upstanding agitating blades extendin upwardly from thebottom of the tub an dlsposed radially with respect to said bafilemember the outer extremities of the top ed es of sai blades being curvedupwardly an inwardly and gradually merged into the contiguous portionsof below the plane of the upper end of said bafile member.

2.In a washing machine, a tub, a centrall located befle member ofrelatively smal diameter'extending upwardly from the radially withrespect to said baflle member,

bottom of the tub, and a plurality of up standing agitating bladesextendm upwardfrom the bottom of the tub an disposed the innerextremities of the top edges of said blades being extended downwardly tothe bot- ,tom of the tub at positions spaced radially from said batllemember, the outer extremities of the top edges of said blades beingcurved upwardly and inwardly and gradually merged into contlguousportions of the .sides of the tub at positions below the plane of theupper end of said bafile member.

3. In a washing machine, a tub having the lower portion of its side wallcurvedinwardl and gradually merged into the bottom 0 the tub, acentrally located baflle member of relatively small diameter extendingupwardly from the bottom of the tub, and a plurality of upstandingagitating blades also extending upwardly from the bottom of the. tub anddisposed radially with respect to said bafile member, the outerextremities of the top edges of said blades being curved upwardly andinwardly and gradually merged into contiguous portions of the sides ofthe tub.
